1. A method comprising:
- providing a substrate comprising a composite layer, the substrate being formed to provide at least one bending wave therein in response to receiving a vibration energy sufficient to cause the at least one bending wave in the substrate; and
converting at least a portion of the vibration energy sufficient to cause the at least one bending wave to at least one shear wave in a portion of the composite layer;
wherein the composite layer comprises an elastomeric polymer matrix comprising carbon nano tubes dispersed or distributed therein.

Abstract
Methods for vibration and acoustic abatement. The methods comprise providing a substrate with a composite layer deposited thereon, the substrate receiving a vibration energy sufficient to provide at least one bending wave therein, and converting at least a portion of the vibration energy sufficient to cause the at least one bending wave to at least one shear wave in at least a portion of the composite layer. The composite layer comprises an elastomeric polymer matrix comprising carbon nano tubes dispersed or distributed therein. Articles with the composite layer comprising carbon nano tubes disposed thereon are also disclosed and described.
